Overview
A compact 5.5 lb capacity portable washer with a separate spin dryer basket, a rotary timer control, a drain tube, and a clear lid, built for spaces without full-size laundry hookups like RVs, dorms and apartments.
This is a manual two-step machine rather than a fully automatic one. It does not shut off water by itself while filling, so it needs to be watched, and clothes must be transferred by hand from the wash tub to the spin basket. Several long-term users, including a full-time RV dweller, describe it as reliable for small loads when actively supervised.
- 5.5 lb wash capacity
- Rotary timer, up to 10-minute wash and 5-minute spin
- Separate wash tub and spin basket
- Includes a drain tube for emptying
Who it's for
Fits apartment or RV dwellers without hookups who wash small loads and don't mind hands-on operation. Not a fit for anyone expecting a hands-off, fully automatic wash-to-dry cycle or planning to wash bulky items like jeans in volume.
What buyers say
From Amazon customer reviews.
Long-term users, including someone living full-time in an RV, describe it as a genuine daily workhorse for small loads once you learn its quirks, praising the price and footprint. Recurring complaints include the spin basket shaking or walking during the spin cycle, a fill hose that does not fit many household faucets, needing to stay nearby while it fills since it will not stop on its own, and spin results that some call hit or miss on heavier loads.
